FreeBSD 5.3/4 vs 4.11

[ray at redshift.com]

Hello list,

  I've recently been doing quite a few benchmarks with regard to PHP and Apache,
as well as stripping down the Kernel on 5.3 and 5.4 to improve performance for
web/application servers.  

My question is: I was wondering if anyone out there has ever done a head to head
test of 4.11 to 5.3 (or 5.4) and if so, is 4.11 faster in any areas and/or does
it provide any benefits over 5.3+?

Thanks.

Ray
